We want to add cedar trim to our front porch. I read that cedar is an excellent wood for exterior use. But do we have to put on a wood perservative or an exterior clear to protect it from the weather in Northeastern Ohio ? Thanks in advance.
An answer that will start with "it depends". If you want to the cedar to remain the nice clean cut looking color, the yes, you may. You will want to sand it first to make the wood nice and smooth. If you want the wood to turn a nice petina gray, which cedar will turn naturally, then no.
I hope that you used stainless steel nails to secure the cedar, or you will have rust in about 6 months, and it will ruin the wood and look of the house. There is no paint that will cover rust. We have a mohogany porch on our Victorian house, that has been there for just over 125 years. All that we do to the wood is apply oil about every other year. We like it to look like fresh cut wood. Cedar will last approx 80 years, that I know of.
